The future shift

[zullil]

Your SF definitely hallucinates, as white has an easy draw here with h5

[d]2b2rk1/2n2p1p/5Pp1/1q1pP1PP/2pP1N2/1pP5/6B1/2Q2RK1 b - - 0 5

but I am currently looking for a way to win.

No doubt the win is there in some of the lines, but you should concentrate very hard to find it.
So far I am unable to do it, but the win is there.

Back for a bit more. SF plays b2 with evaluation 62cp for Black:
[d]2b2rk1/2n2p1p/5Pp1/1q1pP1PP/2pP1N2/2P5/1p4B1/2Q2RK1 w - - 0 6

This is not interesting, Qe1 and there is a forced draw, you might want to check with deeper search. But seemingly f6 also does not lead to a win for white, actually I do not like the move very much.

Am trying to see what second move white should play after Nh5 Nc7, when I find it I will be back.

[Lyudmil Tsvetkov]

OK, my second move after Nh5 Nc7 is Kh1

[d]2bq1rk1/2n2ppp/8/3pPPPN/2pP4/1pP5/6BP/2Q2R1K b - - 0 2

How does black defend here?

Nb5 Qd2 or
Qe8 Bh3

Other moves seem even worse.

Now, I do not say white necessarily wins this, but I can't imagine black holds.

SF has been searching while I was away. It agrees that Qe1 is best for White, but doesn't (yet) see a clear draw:

There is a clear draw, look where your line ends.

In the other line with Kh1, I get a position like that:

[d]2bqnrk1/5ppp/8/3pPPPN/2pP4/1pP4B/7P/2Q3RK w - - 0 7

well, I do not see a forced win, not yet, but is it possible that black hold here, all white pieces attacking, 3 storming pawns, all black pieces on the 8th rank, all black has is a tremendous passer, but that is all?

Is it possible that white does not win here?

[zullil]

OK, my second move after Nh5 Nc7 is Kh1

[d]2bq1rk1/2n2ppp/8/3pPPPN/2pP4/1pP5/6BP/2Q2R1K b - - 0 2

How does black defend here?

SF is searching now, and will reply soon.

Let it search longer, it might take a while while I reply.

SF plays Ne8 with evaluation 0.
[d]2bqnrk1/5ppp/8/3pPPPN/2pP4/1pP5/6BP/2Q2R1K w - - 1 3

I'll let the search continue, in case SF sees something before you reply.

[zullil]

In the other line with Kh1, I get a position like that:

[d]2bqnrk1/5ppp/8/3pPPPN/2pP4/1pP4B/7P/2Q3RK w - - 0 7

Looks like you gave yourself an extra tempo, since you have the rook on g1 and the bishop on h3.

[EDIT] Two tempi, since you also have White to move. Remember, chess is an adversarial game---your opponent gets to move too.

That's exactly what I thought too, when I first saw it, the black Knight might have gone to e8 and back and to b5 and back and to e8 again.


BTW, after 24.Kh1 Black could have had (almost) forced 3fold with ...Nb5,
(instead of your SF's ..Ne8) if he had wanted to:

24.Kh1 Nb5 25.Qe3 Na3 26.Qc1 Nb5
